C# Tutorial - Webcam Face Detection for .NET using EMGU.CV in C# | FoxLearn

Webcam Face Detection for .NET using EMGU.CV, AForge.Video, AForge.Video.DirectShow in C# .NET Windows Forms Application.

We will use the AForge.Video, AForge.Video.DirectShow to capture image from the webcam, EMGU.CV to detect faces.

The AForge.Video library contains interfaces and classes to access different video sources, such as IP video cameras (MJPEG streams). The library defines types used by other video related libraries from AForge.NET framework.

The AForge.Video.DirectShow library contains classes, which allow to access video sources using DirectShow interface (USB web cameras, capture devices, video files, etc.).

Emgu CV is a cross platform .Net wrapper to the OpenCV image processing library. Allowing OpenCV functions to be called from .NET compatible languages such as C#, VB, VC++, IronPython etc.

just a tip for anyone following this tutorial, I had a lot of problems when using the latest versions of EMGU, but then I tried the older versions, such as 3.2 and it worked just fine :3

Hi, great tutorial.
Thanks a lot!
Just a little tip for followers: "Use Emgu.CV V4.1.1.3497 (as in the video) to avoid errors with related functions".

@FoxLearn is there a way to have 2 different types of boxes come up?
Say a red box would appear if the image is in a file directory and a blue box if it is not?
If so how would this be done? If that can't be done, then could you show a way to have a box appear but only on people who the programme has been "trained" to see?

We need a project that compares the face, for example: - You have a group of photos of certain people, the number of thousands, and you take a picture of a modern person, the program compares the new image with the old photos and extracts the old image of his
I think it's termed "image processing"

[tamhoangminh]

Thankyou so much but I had an problem:
I downloaded file in the link github you've share but It still cannot detected my face,
I added checkpoint that cascadeClassifier.DetectMultiScale(grayImage, 1.2, 1) always return empty array. Help me please

Good job with the tutorials, there is really cool videos on your channel.

Would be possible to upload more WPF videos please?

[mohammadthaher]

great video
is there any video or project for medical face detection using emgu.cv c#?

[macximus-zo]

Wow! This is a wonderful tutorial... Thank you FoxLearn!

By the way, is it possible to compare the face from the image saved in the database using that method? If a face was similar on one of the image saved in database, then it will say something! I hope you can make a tutorial for that.😁😊

So wonderful. Hi, do you know how I can stream the processed content ( the frames with rectangules over the smiles) to a client from a Web Server using emgucv ???

Do you try with a Decklink card & Professional SDI Camera?
